Without delay, let's solve this. We've got 741 and we will be multiplying it by 40, that is, adding 741 to itself 40 times.
Step 1: 0 + 741 = 741
Step 2: 741 + 741 = 1482
Step 3: 1482 + 741 = 2223
Step 4: 2223 + 741 = 2964
Step 5: 2964 + 741 = 3705
Step 6: 3705 + 741 = 4446
Step 7: 4446 + 741 = 5187
Step 8: 5187 + 741 = 5928
Step 9: 5928 + 741 = 6669
Step 10: 6669 + 741 = 7410
Step 11: 7410 + 741 = 8151
Step 12: 8151 + 741 = 8892
Step 13: 8892 + 741 = 9633
Step 14: 9633 + 741 = 10374
Step 15: 10374 + 741 = 11115
Step 16: 11115 + 741 = 11856
Step 17: 11856 + 741 = 12597
Step 18: 12597 + 741 = 13338
Step 19: 13338 + 741 = 14079
Step 20: 14079 + 741 = 14820
Step 21: 14820 + 741 = 15561
Step 22: 15561 + 741 = 16302
Step 23: 16302 + 741 = 17043
Step 24: 17043 + 741 = 17784
Step 25: 17784 + 741 = 18525
Step 26: 18525 + 741 = 19266
Step 27: 19266 + 741 = 20007
Step 28: 20007 + 741 = 20748
Step 29: 20748 + 741 = 21489
Step 30: 21489 + 741 = 22230
Step 31: 22230 + 741 = 22971
Step 32: 22971 + 741 = 23712
Step 33: 23712 + 741 = 24453
Step 34: 24453 + 741 = 25194
Step 35: 25194 + 741 = 25935
Step 36: 25935 + 741 = 26676
Step 37: 26676 + 741 = 27417
Step 38: 27417 + 741 = 28158
Step 39: 28158 + 741 = 28899
Step 40: 28899 + 741 = 29640

So, 741*40 = 29640
